LOTUS® POSTERIOR CERVICAL/THORACIC SPINAL SYSTEM IMPLANTS AND INSTRUMENTATION This package insert covers the Lotus® Posterior Cervical/Thoracic Spinal System and Manual Surgical Instruments that are used for the implantation of this system. GENERAL INFORMATION The Lotus Posterior Cervical/Thoracic Spinal System consists of a variety of fixation devices manufactured from Ti-6Al-4V that are attached to the spine. Screws may be placed from a posterior approach into the cervical and/or thoracic spine. Hooks may be placed on the posterior elements of the various vertebrae. Rods span the distance between the screws/hooks, and various other connectors may be used between rods or between rods and screws/hooks. The system achieves fixation by the mechanical joining of the rods, screws, hooks and connectors. A variety of constructs may be assembled to suit the individual pathology and anatomy of the patient. All implants are intended for single patient use only and should not be reused (used in additional patients) under any circumstances. INDICATIONS The Spinal Elements Lotus Posterior Cervical/Thoracic Spinal System is intended to provide immobilization and stabilization of spinal segments as an adjunct to fusion for the following acute and chronic instabilities of the cervical spine (C1 to C7) and the thoracic spine from T1-T3: traumatic spinal fractures and/or traumatic dislocations; instability or deformity; failed previous fusions (e.g., pseudarthrosis); tumors involving the cervical/thoracic spine; and degenerative disease, including intractable radiculopathy and/or myelopathy, neck and/or arm pain of discogenic origin as confirmed by radiographic studies, and degenerative disease of the facets with instability. The Lotus Posterior Cervical/Thoracic Spinal System is also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical spine in whom life expectancy is of insufficient duration to permit achievement of fusion. In order to achieve additional levels of fixation, the Lotus Posterior Cervical/Thoracic Spinal System may be connected to the Mercury® or Overwatch® Spinal System with the Lotus Posterior Cervical/Thoracic rod connectors. Transition rods with differing diameters may also be used to connect the Lotus Posterior Cervical/Thoracic Spinal System to the Mercury Spinal System. Refer to the Mercury Spinal System package insert for a list of the Mercury Spinal System indications for use. CONTRAINDICATIONS 1. Patients with known or probable intolerance to the materials used in the manufacture of this device. 2. Patients with infection, inflammation, fever, tumors, elevated white blood count, obesity, pregnancy, mental illness and other medical conditions which would prohibit beneficial surgical outcome. 3. Patients resistant to following post-operative restrictions on movement especially in athletic and occupational activities. 4. Use with components from other systems. This system is manufactured from titanium alloy. It should not be used in combination with stainless steel components. 5. Grossly distorted anatomy caused by congenital abnormalities. 6. Any patient that has had prior fusion surgery at the levels to be treated. 7. Any other medical or surgical condition which would preclude the potential benefit of spinal implant surgery. 8. Rapid joint disease, bone absorption, osteopenia. Osteoporosis is a relative contraindication since this condition may limit the degree of obtainable correction, stabilization, and/or the amount of mechanical fixation. 9. Any case where the implant components selected for use would be too large or too small to achieve a successful result. 10. Any patient having inadequate tissue coverage over the operative site or inadequate bone stock or quality. 11. Any patient in which implant utilization would interfere with anatomical structures or expected physiological performance. 12. Any case not described in the indications for use. 13. Reuse or multiple use. WARNINGS Implants and instruments are provided non-sterile and must be cleaned and sterilized before use. Validated sterilization cycle parameter protocols are noted in the STERILIZATION section of this insert. Some instruments may be sharp, depending on their intended use. Care should be taken in handling such instruments to avoid injury to the user or patient. A successful result is not always achieved in every surgical case. This fact is especially true in spinal surgery where many extenuating circumstances may compromise the results. System components are temporary implants used for the correction and stabilization of the spine. This system is intended to be used to augment the development of a spinal fusion by providing INS-PCT

temporary stabilization. This system is not intended to be the sole means of spinal support. Use of this product without a bone graft or in cases that develop into a non-union will not be successful. No spinal implant can withstand body loads without the support of bone. In this event, bending, loosening, disassembly, and/or breakage of the device(s) will occur. Warning: The safety and effectiveness of pedicle screw spinal systems have been established only for spinal conditions with significant mechanical instability or deformity requiring fusion with instrumentation. These conditions are: significant mechanical instability or deformity of the thoracic, lumbar, and sacral spine secondary to severe spondylolisthesis (grades 3 and 4) of the L5S1 vertebra; degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor; and failed previous fusion (pseudoarthrosis). The safety and effectiveness of these devices for any other conditions are unknown. Implantation of the device should be performed only by experienced spinal surgeons with specific training in the use of this device. This is a technically demanding procedure presenting a risk of serious injury to the patient. Preoperative and operating procedures including knowledge of surgical techniques, proper reduction, and proper selection and placement of the implant are important considerations in the successful utilization of this device by the surgeon. Further, the proper selection and compliance of the patient will greatly affect the results. The physician should consider the levels of implantation, patient weight, patient activity level, and all other patient conditions that may have an impact on the performance of this device. Patients who smoke have been shown to have an increased incidence of non-union. These patients should be advised of this fact and warned of this consequence. Obese, malnourished, and/or alcohol abuse patients are also poor candidates for spine fusion. Patients with poor muscle and bone quality and/or nerve paralysis are also poor candidates for spine fusion. Patients who have had previous spinal surgery at the level(s) to be treated may have a worse clinical outcome compared to those without previous surgery at the levels to be treated. Note: Components of this system should not be used in conjunction with other systems unless specifically specified in this package insert. Physician Note: The physician is the learned intermediary between the company and the patient. The indications, contraindications, warnings, and precautions given in this document must be conveyed to the patient. MAGNETIC RESONANCE ENVIRONMENT The Lotus Posterior Cervical/Thoracic Spinal System has not been evaluated for safety and compatibility in the MR environment. It has not been tested for heating, migration, or image artifact in the MR environment. The safety of the device in the MR environment is unknown. Scanning a patient who has this device may result in patient injury. PREOPERATIVE MANAGEMENT 1. The surgeon should consider for surgery only those patients indicated for the use of this device. 2. The surgeon should not consider for surgery those patients contraindicated for the use of this device. 3. The surgeon should have a complete understanding of the device’s indications, contraindications, and applications. 4. The surgeon should have a complete understanding of the function and limitations of each implant and instrument. 5. Use of cross sectional imaging (i.e., CT and/or MRI) for posterior cervical screw placement is recommended due to unique risks in the cervical spine. The use of planar radiographs alone may not provide the necessary imaging to mitigate the risk of improper screw placement. In addition, use of intraoperative imaging should be considered to guide and/or verify device placement as necessary. 6. Device components should be received and accepted only in packages that have not been damaged or tampered with. Damaged implants and/or instruments should not be used. All implants and instruments should be inspected prior to use. Components must be carefully handled and stored in a manner that prevents scratches, damage, and corrosion. 7. The type of implant to be used for the case should be determined prior to beginning the surgery. 8. All instruments should be cleaned and sterilized prior to use. INTRAOPERATIVE INSTRUCTIONS 1. Extreme caution should be used around the spinal cord and nerve roots. Damage to the nerves will cause loss of neurological functions. 2. Breakage, slippage, or misuse of instruments or implant components may cause injury to the patient or operative personnel. 3. Implants should be attached to the corresponding inserter such that they are fully seated on the inserter. Care should be taken not to over-tighten the implant to the inserter. 4. Whenever possible or necessary, an imaging system should be utilized to facilitate surgery. 5. Caution should be taken in handling the implants. Damage to the implants may affect their performance. 6. Implants should not be reused under any circumstances.

SINGLE USE Reuse of a single use device that has come in contact with blood, bone, tissue or other body fluids may lead to patient or user injury. Possible risks associated with reuse of a single use device include, but are not limited to, mechanical failure, serious injury, transmission of infectious agents and death. Implants that have directly come in contact with the patient or bio-contaminants should be discarded. Separate inserts for implants from the instrument tray prior to and during any processing. CLEANING AND MAINTENANCE GENERAL INFORMATION Spinal Elements’ instruments are manufactured from various stainless steels, aluminums, and polymers. All materials used have a history of use in such instruments. CLEANING AND MAINTENANCE All devices must be free of packaging material prior to sterilization. All instruments must be free of bio-contaminants prior to sterilization. Implants exposed to bio-contaminants should be disposed of. Cleaning, maintenance and mechanical inspection must be performed by hospital personnel trained in the general procedures involving contaminant removal. Only neutral pH cleaners or detergents labeled for use in cleaning medical devices should be used for cleaning components. Only lubricants that are intended for use on surgical instruments should be used to lubricate instruments. Follow directions from the manufacturer of the lubricating and cleaning agents regarding handling, concentration, and use of such agents. Cleaning instructions are provided in accordance with recognized standards and regulations and are intended to supplement a hospital’s existing device cleaning and disinfecting protocol. Contaminated devices should be wiped clean of visible soil at the point of use prior to transfer to a central processing unit for cleaning and sterilization.
